This study conducted to evaluate the toxic effects of a widely used oxadiazon herbicide,on common carp (Cyprinus carpio) fingerling (15 g). The 96-h LC_50 was determined, and the growth performance, serum biochemical and hematological parameters, DNA damage of erythrocytes cells, as well as histopathological changes were also determined in fish exposed to sublethal concentrations (1, 1.5 and 2 ppm) of the herbicide for 30 days. The 96-h LC_50 to C. carpio was found to be 3.9 ppm. Weight gain (WG), specific growth rate (SGR) and condition factor (CF) were decreased, while food conversion ratio (FCR) increased in the exposed fish groups (P< 0.05). Erythrocytes cells of fish exposed to 1, 1.5 and 2 ppm of oxadiazon showed DNA damage (21.3%, 22.9%, and 28.4%, respectively), significantly higher than control group (p < 0.05). Moreover, exposure to oxadiazon significantly decreased WBC, RBC, Hb, Hct as well as serum albumin, glucose, and total protein levels, while serum ALP was significantly increased in the exposed fish groups (
